(Alliance News) - The following stocks are the leading risers and fallers on AIM in London on Friday.

AIM - WINNERS

----------

Gelion PLC, up 18% at 30.70 pence, 12-month range 14.00p-39.70p. The stock builds on its 70% jump from Thursday. Gelion on Thursday said it achieved a milestone with its lithium-sulphur battery development, increasing its energy density by around 60%. The London-based battery technology company said this was by fabricating a 395 watt-hour per kilogram lithium-sulphur 9.5 ampere-hour pouch cell in a commercial cell format. Gelion said the energy density increase is compared with current lithium-ion batteries, which provide around 250 watt-hours per kilogramme. "Achievement of this milestone represents a key technology proof point for Gelion," it said.

AIM - LOSERS

----------

Steppe Cement Ltd, down 17% at 17.00p, 12-month range 17.00p-45.90p. The Kazakhstan-focused cement producer says it sold KZT3.78 billion, around USD8.4 million, worth of cement in the first-quarter, down 23% from a year prior. "Steppe Cement's market share decreased to 11.5% in the first quarter of 2024 compared with 12.7% in the first quarter of 2023," it adds. "Transportation costs have increased significantly and shipments to the southern region of Kazakhstan result in low margins. The cement market in winter is comparatively small in the northern regions of Kazakhstan compared with the summer season, and therefore the company, which has been operating at full efficiency over the quarter, has chosen to build up clinker inventory in preparation of the summer season, rather than make sales at depressed prices."

----------

Keywords Studios PLC, down 0.7% at 1,191.96p, 12-month range 1,175.00p-2,800.00p. Shares in the services provider to the video game industry are on track to suffer a fourth-successive decline. The stock hits this 12-month low on Friday and has fallen 53% over the past year. Consensus opinion on the stock is largely positive, however.
